Fig. 1 The chemical structure of deltamethrin
Pyrethroids are a class of biomimetic pesticides synthesized by structural modification of natural pyrethrins and are widely used in the prevention and control of various crop diseases and insect pests. Such pesticides include cypermethrin, lambda-cyhalothrin, rich-d-trans allethrin, etc. Pyrethroid contaminants mainly come from extensive use in agricultural production. In addition, the waste gas, wastewater, and waste discharged by enterprises that produce and process such pesticides are also the source of the contaminant. After a large amount of pyrethroid vinegar enters the environment, it is easy to accumulate in the environment for a long time and is leached and penetrated sedimentary rocks and groundwater through rainwater, causing water and soil pollution. Studies have shown that pyrethroids not only accumulate, but long-term exposure can also cause many chronic diseases in the human body.
Pyrethroids are fat-soluble pesticides, which can not only accumulate in crops, even endanger animal and human health through the food chain. Acute poisoning symptoms are mainly manifested as neurological symptoms and skin symptoms. Nervous system symptoms include short-term unresponsiveness, fatigue, dyskinesia, palpitations, and then general excitement and convulsions. Skin symptoms are mostly localized allergies, red rashes, and tingling sensation around the eyes, nose, mouth, and contact parts. Pyrethroids enter the human body through the food chain and accumulate in the human body, causing carcinogenic, squirting, mutagenic, and other hazards. To prevent pyrethroids from continuing to pollute the environment and endanger biological health, ELISA can be used to detect the concentration of pyrethroids in environmental samples, and timely monitoring of such contaminants.
